Refrigerator with electrodeless dual-frequency compressor

Abstract

The invention provides a refrigerator with an electrodeless dual-frequency compressor, and belongs to the technical field of refrigeration equipment. The refrigerator with the electrodeless dual-frequency compressor solves the problem that a refrigerator can not operate under wide voltage and double frequencies. The refrigerator with the electrodeless dual-frequency compressor comprises a refrigerator body, an inner container, the compressor, a condenser and an evaporator, wherein the compressor, the condenser and the evaporator are sequentially connected to form a circulation loop. The refrigerator with the electrodeless dual-frequency compressor is characterized in that the compressor comprises a power source, a motor, a PTC starter, a heat protector and a switch protector; the heat protector and the switch protector are arranged between the shared leading-out end of the motor and the power source; the PTC starter is arranged between the running winding leading-out end of the compressor and the starting winding leading-out end of the compressor. The refrigerator with the electrodeless dual-frequency compressor can be applicable to various voltages and frequencies, and is wide in usage range. In addition, the refrigerator with the electrodeless dual-frequency compressor can effectively achieve the purposes of heating protection and temperature control over the motor of the compressor, and improve the using safety.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and relates to a refrigerator, in particular to a refrigerator with a stepless dual-frequency compressor. Background technique [0002] With the deepening of economic globalization, my country's home appliances have spread all over the world. According to statistics, in 2012, the sales and export volume of my country's refrigerators and freezers was 33.24 million units. However, the voltage and frequency of power grids in different countries and regions vary greatly. For example, the voltages are: 100V / 110V / 127V / 115V / 220-240V; the frequency is 50HZ / 60HZ, and there are voltage instability problems in some countries and regions, which bring great hidden dangers to the start-up and safe operation of the compressor, so Higher requirements are put forward for the compressor of the freezer. More and more customers are choosing wide voltage and dual frequency in their orders. If the proble...

However, the voltage and frequency of power grids in different countries and regions vary greatly. For example, the voltages are: 100V / 110V / 127V / 115V / 220-240V; the frequency is 50HZ / 60HZ, and there are voltage instability problems in some countries and regions, which bring great hidden dangers to the start-up and safe operation of the compressor, so Higher requirements are put forward for the compressor of the freezer. More and more customers are choosing wide voltage and dual frequency in their orders. If the problems of heating protection and temperature control cannot be effectively solved, it will bring safety hazards. Traditional compressors can no longer meet the requirements of the global market
